In this VIS image, taken by the NASA - Mars Odyssey Orbiter on September, 30th, 2014, and during its 56.765th orbit around the Red Planet, we can see a large Field of Layers located in the South Polar Cap. More than abundant traces of Residual Carbon Dioxide (CO2) Ice and a few areas covered by orangish Dust which are now Frost-free can also be seen all over the area. Furthermore, several different kinds of Surface Textures (from the so-called "Swiss-Cheese Terrain" to the "South Polar Layered Deposits" - or "SPLD", for short - with their abundant "Unconformities") can also be seen and esaily spotted and recognized.

This image (which is a crop taken from an Original Mars Odyssey Orbiter b/w and Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 18955) has been additionally processed, magnified to aid the visibility of the details, contrast enhanced and sharpened, Gamma corrected and then colorized in a New Version of Absolute Natural Colors (such as the colors that a human eye would actually perceive if someone were onboard the NASA - Mars Odyssey Orbiter and then looked down, towards the Surface of Mars), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team.
